Baseline Model Establishment for a Bridge: II. Static Load Testing
Truck load testing is a field experimentation technique used widely for bridge load rating. For new bridge infrastructure, a baseline model developed through dynamic or static load testing can be used as a reference for long-term structural performance monitoring. This paper presents a study of truck load testing on a hybrid HPS steel girder bridge. The negative moment region of the girder is composed of HPS 100W steel in the flanges and HPS 70W steel in the web. A non-contact laser sensing technique was used to measure bridge deformation under static loads. The experimental results were compared with a numerical model for validation purposes. Static load testing, along with dynamic analysis reported in a companion paper, was used to create benchmark information for this structure that will be useful for future bridge inspection.
